Large Recurrent Benign Mixed Tumor of Parotid Gland

Abstract

This review study described clinical outcomes of superficial parotidectomy in patients with non-previous surgery and previous surgery with large recurrent mass of benign mixed tumor of parotid gland and the interesting case with large recurrent tumor was presented. Between October 1998 and September 2007, 19 patients were treated by the author at Chaoprayayomraj Hospital. There were 13 patients (68.4%) non-previous surgery and 6 patients (31.6%) previous surgery with large recurrent tumor. Previous surgeries were local excision (5/6) and superficial parotidectomy (1/6). The average size of non-previous and previous surgery tumors were 3.7 cm, and 6.2 cm. respectively. The benign mixed tumors located at superficial lobe of parotid gland were found in all patients. This study show that eventhough many provincial hospitals do not have nerve monitoring during surgery but the facial nerve preservation carefully could be well success. 1 patient (7.7%) with non-previous surgery had neurapraxia of zygomatic branch and 1 patient (16.7%) with previous-surgery had neurapraxia of mandibular branch. After followed up, all patients were not found recurrent  and complication.
